In r21611, about 3 years ago, the switch into protected mode was moved
from stage1 to stage2, which makes stage1 obsolete. You have to use
"pxehaiku-loader" when booting Haiku by PXE on x86.
Trying to use stage1 to boot stage2 resulted in tripple fault during
setup of ss segment, because stage1 switches to protected mode before
calling stage2, but stage2 expects real mode. The documentation is not
up to date.

- This is mostly a copy of the x86 32bit paging method and infrastructure, this was copied for two reasons:
1) It is the most complete VM arch
2) The first ARM PAE patches have landed on alkml, so we will have to deal with it in the future as well,
and this infrastructure has proven to be ready ;)
- No protection features, or dirty/accessed tracking yet
- Lots of #if 0
but....
It boots all the way up to init_modules() now, and then dies because of a lack of (ARM) ELF relocation implementation!

If no Haiku remote disk server is found, try an iSCSI discovery session on
the TFTP server, using the IP address from the boot command or OF options.
All available IPv4 targets are considered, Target Portal Groups are ignored.
RFC 4173 suggests a mechanism that avoids a discovery session by using DHCP;
that requires a compatibly configured DHCP server though and we wouldn't have
access to such data currently anyway. iSCSI is currently used as fallback,
and when it doesn't succeed it falls back to the menu as before.

Don't enqueue a packet whose sequence number matches the first one in queue
or is between the next and the acknowledged on. This would lead to packet
duplication in the queue and leftovers after dequeuing.
Optimize calculation of acknowledgement number for out-of-order reception.
If a single missing packet arrived, this could have resulted in a timeout
depending on the window size.
In case the connection is closed, do dequeue remaining packets. This would
have caused a read error after a unidirectional FIN.
Prepare a dynamic window size calculation.
Do checksum calculation before attempting to trace packet contents. I have
seen a few and couldn't spot an error in the checksum calculation.

Modelled after UDP, add limited TCP support to the boot net stack. The socket
works by queuing received packets as well as sent packets that have not yet
been ACK'ed. Some known issues are documented, especially there's only limited
congestion control. I.e., we send immediately and in unlimited quantity, thus
its use should be restricted to local networks, and due to a fixed window size
there is potential for our socket being overrun with data packets before they
are read. Some corner cases like wrapping sequence numbers may cause a timeout.
The TCP implementation is based on Andrew S. Tanenbaum's "Computer Networks",
4th ed., as well as lecture notes from Prof. W. Effelsberg, the relevant RFCs
and Wikipedia. The pseudo-random number Galois LFSR used for the sequence
number was suggested by Endre Varga.
Since the code is unlikely to get much smaller, better merge it now so that
subsequent changes get easier to review. No platform actively uses TCP sockets
yet, and the receiving code has been reviewed for endianness issues and should
terminate okay after verifying the checksum if no sockets are open.
Based on a version tested with custom code (#5240) as well as with iSCSI.
Compile-tested boot_loader_openfirmware, pxehaiku-loader with gcc4 and
haiku_loader with gcc2. Closes ticket #5240.
Changes from #5240 proposed patch:
* Various bug fixes related to queuing, some memory leaks fixed.
* Never bump the sequence number when dequeuing a packet. It's done afterwards.
* Don't bump the sequence number again when resending the queue or ACK'ing.
* Aggressively ACK while waiting for packets.
* Don't queue sent ACK-only packets.
* More trace output, esp. for queue inspection.
* Adapted use of TCP header flags to r38434.

system_time() was based on of_milliseconds(), which returns the number of
milliseconds since power-on. This would produce very similar or identical
results for subsequent boots due to limited clock resolution; therefore it
was unsuited as PRNG seed, e.g., for TCP ports.
Try to inquire the RTC device node with get-time to return an improved time
value, if possible.
